MFC treating customers like *********

I am beyond disappointed in this company. My car is behind with half a month's installment and I have emailed them explaining that it will be brought fully up to date end of May. They have been delivering letters to my house via "tracers" like I am some sort of ********! I then contacted the call centre asking them to look into my account which they did. I then got an email from a collections officer named Tania Simon. I emailed her back explaining I don't have access to my cellphone during office hours and explained the situation with her in detail via email. I also mentioned that the account it will be brought up to date. She never acknowledged my email nor did she respond. Just to hear today another letter was dropped at my house. When did I attempt to flee the country??? I am disgusted in the way you treat your customers and I couldn't help but notice 99.9% of the reviews are of similar customers feeling the level of disgust and disappointment I am feeling now. Why do you treat your customers like that? I would have expected this treatment if I was behind 3 or more months. You can definitely learn something from other vehicle finance companies.
